Aramid Cuff Flame Resistant Accessories With Elastic

1. Description:

Dry spinning method: dissolve the polymer in DMF or DMA, and then add some chloride (into LiCL) as auxilaries to get the spinning stock. After spinning by spinneret, filament or staple fiber can be prepared by washing with water for many times and drawing 4~5 times at 300 ℃ because of the large amount of inorganic salts on the surface of the primary fiber.

Wet spinning method: DMF is also used as the solvent to dissolve the polymer to prepare the spinning stock. After spinneret spinning, the raw silk enters the solidification liquid containing DMF and CaCL2 to obtain the primary fiber, and then is stretched 2.73 times in hot water and dried by hot roller. After stretching 1.45 times on the hot plate, the product is obtained, and the finished product is mainly short fiber.

3. Characters of the products:

Excellent electrical insulation.

Aramid 1313 has a very low dielectric constant, and its inherent dielectric strength enables it to maintain excellent electrical insulation under high temperature, low temperature and high humidity conditions. The breakdown voltage of insulating paper prepared by aramid 1313 can reach 100,000 V/mm, which is recognized as the best insulating material in the world.

Excellent chemical stability.

Aramid 1313 is a linear macromolecule composed of amide bonds connected to aryl groups. In its crystal, hydrogen bonds are arranged into a three-dimensional structure in two planes. This strong hydrogen bond makes its chemical structure extremely stable and can resist the corrosion of most high concentration inorganic acids and other chemicals, hydrolysis and steam corrosion.
